Measurements of the Absolute Branching Fractions of B^±→K^±X_(cc) [PDF]

, 2006
We study the two-body decays of B^± mesons to K^± and a charmonium state X_cc in a sample of 210.5  fb^(-1) of data from the BABAR experiment. We perform measurements of absolute branching fractions B(B^±→K^±X_(cc)) using a missing mass technique, and ...

Understanding the spectral hardenings and radial distribution of Galactic cosmic rays and Fermi diffuse gamma-rays with spatially-dependent propagation

, 2018
Recent direct measurements of Galactic cosmic ray spectra by balloon/space-borne detectors reveal spectral hardenings of all major nucleus species at rigidities of a few hundred GV. The all-sky diffuse gamma-ray emissions measured by the Fermi Large Area

Measurement of time-dependent CP asymmetry in B^0→K_S^0π^0γ decays [PDF]

, 2008
We measure the time-dependent CP asymmetry in B^0→K_S^0π^0γ decays for two regions of K_S^0-π^0 invariant mass, m(KS0π0), using the final BABAR data set of 467×10^6 BB pairs collected at the PEP-II e^+e^- collider at SLAC.

Model-independent extraction of form factors and |Vcb|

Physical Review D
Using the entire ϒ(4S) dataset, the first two-dimensional unbinned angular analysis of the semileptonic decay B¯→Dℓ−ν¯ℓ is performed, employing hadronic reconstruction of the tag-side B meson from ϒ(4S)→BB¯.

A model independent determination of the B -> Xs gamma decay rate

, 2013
The goal of the SIMBA collaboration is to provide a global fit to the available measurements of inclusive B -> X_s gamma and B -> X_u l nu decays. By performing a global fit one is able to simultaneously determine the relevant normalizations, i.e.

Measurement of D^0-D(overbar)^(0) Mixing Parameters Using D^0 → K_(S)^(0)π^(+)π^(-) and D^0 → K_(S)^(0)K^(+)K^(-) Decays [PDF]

We report a direct measurement of D^0-D(overbar)^0 mixing parameters through a time-dependent amplitude analysis of the Dalitz plots of D^0 → K_(S)^(0)π^(+)π^(-) and, for the first time, D^0 → K_(S)^(0)K^(+)K^(-) decays.

Observation of the semileptonic decays B ---> D* tau- anti-nu(tau) and evidence for B ---> D tau- anti-nu(tau [PDF]

, 2007
We present measurements of the semileptonic decays B- --> D0 tau- nubar, B- --> D*0 tau- nubar, B0bar --> D+ tau- nubar, and B0bar --> D*+ tau- nubar, which are potentially sensitive to non--Standard Model amplitudes.

We have searched for the decays B^0 → D_s^+a^-_0, B^0 → D_s^(*+)a^-_0, B^0 → D_s^+a^-_2 and B^0 → D_s^(*+)a^-_2 in a sample of about 230 × 10^6 Υ(4S) → BB̅ decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC.
